MITRE has released its annual list of the Top 25 "most dangerous software weaknesses" for the year 2023. "These weaknesses lead to serious vulnerabilities in software," the U.S. Cybersecurity and Infrastructure Security Agency (CISA)  said . "An attacker can often exploit these vulnerabilities to take control of an affected system, steal data, or prevent applications from working." The  list  is based on an  analysis  of public vulnerability data in the National Vulnerability Data ( NVD ) for root cause mappings to CWE weaknesses for the previous two years. A total of 43,996 CVE entries were examined and a score was attached to each of them based on prevalence and severity. Coming out top is Out-of-bounds Write, followed by Cross-site Scripting, SQL Injection, Use After Free, OS Command Injection, Improper Input Validation, Out-of-bounds Read, Path Traversal, Cross-Site Request Forgery (CSRF), and Unrestricted Upload of File with Dangerous Type. Out-of

The U.S. Cybersecurity and Infrastructure Security Agency has  added  a batch of six flaws to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. This comprises three vulnerabilities that Apple patched this week ( CVE-2023-32434, CVE-2023-32435, and CVE-2023-32439 ), two flaws in VMware ( CVE-2023-20867  and  CVE-2023-20887 ), and one shortcoming impacting Zyxel devices ( CVE-2023-27992 ). CVE-2023-32434 and CVE-2023-32435, both of which allow code execution, are said to have been exploited as zero-days to deploy spyware as part of a years-long cyber espionage campaign that commenced in 2019. Dubbed Operation Triangulation, the activity culminates in the deployment of  TriangleDB  that's designed to harvest a wide range of information from compromised devices, such as creating, modifying, removing, and stealing files, listing and terminating processes, gathering credentials from iCloud Keychain, and tracking a user's location. The

Progress Software on Thursday  disclosed  a third vulnerability impacting its MOVEit Transfer application, as the Cl0p cybercrime gang deployed extortion tactics against affected companies. The  new flaw , which is being tracked as CVE-2023-35708 , also concerns an SQL injection vulnerability that "could lead to escalated privileges and potential unauthorized access to the environment." The company is urging its customers to disable all HTTP and HTTPs traffic to MOVEit Transfer on ports 80 and 443 to safeguard their environments while a fix is being prepared to address the weakness. The cloud managed file transfer solution has been fully patched. The revelation comes a week after Progress  divulged  another set of SQL injection vulnerabilities ( CVE-2023-35036 ) that it said could be weaponized to access the application's database content. The vulnerabilities join  CVE-2023-34362 , which was  exploited  as a zero-day by the Clop ransomware gang in data theft attacks

The threat actors behind the  LockBit  ransomware-as-a-service (RaaS) scheme have extorted $91 million following hundreds of attacks against numerous U.S. organizations since 2020. That's according to a  joint bulletin  published by the U.S. Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), the Multi-State Information Sharing and Analysis Center (MS-ISAC), and other partner authorities from Australia, Canada, France, Germany, New Zealand, and the U.K. "The LockBit ransomware-as-a-service (RaaS) attracts affiliates to use LockBit for conducting ransomware attacks, resulting in a large web of unconnected threat actors conducting wildly varying attacks," the agencies  said . LockBit, which first burst onto the scene in late 2019, has continued to be disruptive and prolific, targeting as many as 76 victims in May 2023 alone, per statistics shared by  Malwarebytes  last week. The Russia-linked cartel has claimed responsibil

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday  placed  two recently disclosed flaws in Zyxel firewalls to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation. The vulnerabilities, tracked as  CVE-2023-33009 and CVE-2023-33010 , are buffer overflow vulnerabilities that could enable an unauthenticated attacker to cause a denial-of-service (DoS) condition and remote code execution. Patches to plug the security holes were released by Zyxel on May 24, 2023. The following list of devices are affected - ATP (versions ZLD V4.32 to V5.36 Patch 1, patched in ZLD V5.36 Patch 2) USG FLEX (versions ZLD V4.50 to V5.36 Patch 1, patched in ZLD V5.36 Patch 2) USG FLEX50(W) / USG20(W)-VPN (versions ZLD V4.25 to V5.36 Patch 1, patched in ZLD V5.36 Patch 2) VPN (versions ZLD V4.30 to V5.36 Patch 1, patched in ZLD V5.36 Patch 2), and ZyWALL/USG (versions ZLD V4.25 to V4.73 Patch 1, patched in ZLD V4.73 Patch 2) While the exa

A stealthy China-based group managed to establish a persistent foothold into critical infrastructure organizations in the U.S. and Guam without being detected,  Microsoft  and  the "Five Eyes" nations  said on Wednesday. The tech giant's threat intelligence team is tracking the activity, which includes post-compromise credential access and network system discovery, under the name  Volt Typhoon . The state-sponsored actor is  geared  towards espionage and information gathering, with the cluster active since June 2021 and obscuring its intrusion footprint by taking advantage of tools already installed or built into infected machines. Some of the prominent sectors targeted include communications, manufacturing, utility, transportation, construction, maritime, government, information technology, and education. The company further assessed with moderate confidence that the campaign is "pursuing development of capabilities that could disrupt critical communications i

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has warned of active exploitation of a medium-severity flaw affecting Samsung devices. The issue, tracked as  CVE-2023-21492  (CVSS score: 4.4), impacts select Samsung devices running Android versions 11, 12, and 13. The South Korean electronics giant described the issue as an information disclosure flaw that could be exploited by a privileged attacker to bypass address space layout randomization ( ASLR ) protections. ASLR is a  security technique  that's designed to thwart memory corruption and code execution flaws by obscuring the location of an executable in a device's memory. Samsung, in an  advisory  released this month, said it was "notified that an exploit for this issue had existed in the wild," adding it was privately disclosed to the company on January 17, 2023. Other details about how the flaw is being exploited are currently not known, but vulnerabilities in Samsung phones have been we

U.S. cybersecurity and intelligence agencies have warned of attacks carried out by a threat actor known as the  Bl00dy Ransomware Gang  that attempt to exploit vulnerable PaperCut servers against the education facilities sector in the country. The attacks took place in early May 2023, the Federal Bureau of Investigation (FBI) and Cybersecurity and Infrastructure Security Agency (CISA) said in a joint cybersecurity advisory issued Thursday. "The Bl00dy Ransomware Gang gained access to victim networks across the Education Facilities Subsector where PaperCut servers vulnerable to  CVE-2023-27350  were exposed to the internet," the agencies  said . "Ultimately, some of these operations led to data exfiltration and encryption of victim systems. The Bl00dy Ransomware Gang left ransom notes on victim systems demanding payment in exchange for decryption of encrypted files." Additionally, the Bl00dy actors are said to have used TOR and other proxies from within victim

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday  released  an Industrial Control Systems (ICS) advisory about a critical flaw affecting ME RTU remote terminal units. The security vulnerability, tracked as  CVE-2023-2131 , has received the highest severity rating of 10.0 on the CVSS scoring system for its low attack complexity. "Successful exploitation of this vulnerability could allow remote code execution," CISA  said , describing it as a case of command injection affecting versions of INEA ME RTU firmware prior to  version 3.36 . Security researcher Floris Hendriks of Radboud University has been credited with reporting the issue to CISA. Also published by CISA is an  alert  related to multiple known security holes in Intel(R) processors impacting Factory Automation (FA) products from Mitsubishi Electric that could result in privilege escalation and a denial-of-service (DoS) condition. The development comes as the agency  recommended  criti

Critical infrastructure attacks are a preferred target for cyber criminals. Here's why and what's being done to protect them. What is Critical Infrastructure and Why is It Attacked? Critical infrastructure is the physical and digital assets, systems and networks that are vital to national security, the economy, public health, or safety. It can be government- or privately-owned. According to Etay Maor, Senior Director Security Strategy at  Cato Networks , "It's interesting to note critical infrastructure doesn't necessarily have to be power plants or electricity. A nation's monetary system or even a global monetary system can be and should be considered a critical infrastructure as well." These qualities make critical infrastructure a preferred target for cyber attacks. If critical infrastructure is disrupted, the impact is significant. In some cases, such cyber attacks on critical infrastructure have become another means of modern warfare. But unlike

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has released eight Industrial Control Systems (ICS)  advisories  on Tuesday, warning of critical flaws affecting equipment from Delta Electronics and Rockwell Automation. This includes 13 security vulnerabilities in Delta Electronics' InfraSuite Device Master, a real-time device monitoring software. All versions prior to 1.0.5 are affected by the issues. "Successful exploitation of these vulnerabilities could allow an unauthenticated attacker to obtain access to files and credentials, escalate privileges, and remotely execute arbitrary code," CISA  said . At the top of the list is  CVE-2023-1133  (CVSS score: 9.8), a critical flaw that arises from the fact that InfraSuite Device Master accepts unverified UDP packets and  deserializes the content , thereby allowing an unauthenticated remote attacker to execute arbitrary code. Two other deserialization flaws,  CVE-2023-1139  (CVSS score: 8.8) and  CVE-20

Multiple threat actors, including a nation-state group, exploited a critical three-year-old security flaw in Progress Telerik to break into an unnamed federal entity in the U.S. The  disclosure  comes from a  joint advisory  issued by the Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), and Multi-State Information Sharing and Analysis Center (MS-ISAC). "Exploitation of this vulnerability allowed malicious actors to successfully execute remote code on a federal civilian executive branch (FCEB) agency's Microsoft Internet Information Services (IIS) web server," the agencies  said . The indicators of compromise (IoCs) associated with the digital break-in were identified from November 2022 through early January 2023. Tracked as  CVE-2019-18935  (CVSS score: 9.8), the issue relates to a .NET  deserialization vulnerability  affecting Progress Telerik UI for ASP.NET AJAX that, if left unpatched, could  lead to remote code exec
